I've had that clunk in every 4wd 4l60e trans I 've owned, this is different than the clunk as you come to a stop or accelerate from a stop, the binding of the front yoke causes this. The 2-3 clunk is caused by a " tolerance" stack in the trans and transfer case combined, never had any problem as a result, never heard of a fix for it and there has been a TSB explaining this for years. There is a lot going on tin the trans in 3-2, 2-3 shifts that aggravate the condition.
